## Abstract

A polarity-inverting telecommunication tap includes a backplate having an input port, an output port, and terminal posts. The input and output ports communicate a signal having a signal polarity. The tap also includes a faceplate having a tap port and having sockets corresponding and complemental to the terminal posts. The tap port communicates a tap signal having a tap signal polarity. The tap further includes an adapter plate disposed between the backplate and faceplate. The adapter plate has an electrical circuit which inverts the tap signal polarity with respect to the signal polarity, so that downstream CATV devices may operate with an intended polarity.

## Claims

### Claim 1

A telecommunication tap comprising:
a backplate having an input port, an output port, and terminal posts, wherein the input and output ports communicate a signal having a signal polarity;
a faceplate having a tap port and having sockets corresponding and complemental to the terminal posts, wherein the tap port communicates a tap signal having a tap signal polarity; and
an adapter plate disposed between the backplate and faceplate, the adapter plate having an electrical circuit which inverts the tap signal polarity with respect to the signal polarity.

### Claim 2 (depends on 1)

The telecommunication tap of claim 1, wherein:
the adapter plate has sockets corresponding and complemental to the terminal posts on the backplate; and
the adapter plate has terminal posts corresponding and complemental to the sockets on the faceplate.

### Claim 3 (depends on 2)

The telecommunication tap of claim 2, wherein:
the terminal posts on the backplate and the adapter plate correspond in location to each other; and
the sockets on the adapter plate and the faceplate correspond in location to each other.

### Claim 4 (depends on 1)

The telecommunication tap of claim 1, wherein the backplate, faceplate, and adapter plate all have an identical peripheral form factor.

### Claim 5 (depends on 1)

The telecommunication tap of claim 1, further comprising:
the backplate has a channel for holding a gasket, the faceplate has a channel for holding a gasket, and the adapter plate has channels on opposed sides of the adapter plate for holding gaskets; and
the channels all correspond in shape and size to each other.

### Claim 6

A telecommunication tap comprising:
a backplate having an input port and an output port, wherein the input and output port communicate a signal having a signal polarity;
a faceplate having a tap port which communicates a tap signal having a tap signal polarity; and
an adapter plate disposed between the backplate and faceplate, the adapter plate having an electrical circuit which inverts the tap signal polarity with respect to the signal polarity.

### Claim 7 (depends on 6)

The telecommunication tap of claim 6, further comprising:
the backplate has terminal posts; and
the faceplate has sockets corresponding and complemental to the terminal posts.

### Claim 8 (depends on 7)

The telecommunication tap of claim 7, wherein:
the adapter plate has sockets corresponding and complemental to the terminal posts on the backplate; and
the adapter plate has terminal posts corresponding and complemental to the sockets on the faceplate.

### Claim 9 (depends on 8)

The telecommunication tap of claim 8, wherein:
the terminal posts on the backplate and the adapter plate correspond in location to each other; and
the sockets on the adapter plate and the faceplate correspond in location to each other.

### Claim 10 (depends on 6)

The telecommunication tap of claim 6, wherein the backplate, faceplate, and adapter plate all have an identical peripheral form factor.

### Claim 11 (depends on 6)

The telecommunication tap of claim 6, further comprising:
the backplate has a channel for holding a gasket, the faceplate has a channel for holding a gasket, and the adapter plate has channels on opposed sides of the adapter plate for holding gaskets; and
the channels all correspond in shape and size to each other.

### Claim 12

A telecommunication tap comprising:
a backplate having an input port and an output port for transmitting a signal therebetween, the signal having a signal polarity;
a faceplate having a tap port which communicates a tap signal having a tap signal polarity; and
an adapter plate disposed in electrical contact between the backplate and the faceplate, the adapter plate communicating the signal and the tap signal between the backplate and the faceplate and inverting the tap signal polarity with respect to the signal polarity.

### Claim 13 (depends on 12)

The telecommunication tap of claim 12, further comprising:
the backplate has terminal posts; and
the faceplate has sockets corresponding and complemental to the terminal posts.

### Claim 14 (depends on 13)

The telecommunication tap of claim 13, wherein:
the adapter plate has sockets corresponding and complemental to the terminal posts on the backplate; and
the adapter plate has terminal posts corresponding and complemental to the sockets on the faceplate.

### Claim 15 (depends on 14)

The telecommunication tap of claim 14, wherein:
the terminal posts on the backplate and the adapter plate correspond in location to each other; and
the sockets on the adapter plate and the faceplate correspond in location to each other.
